To cvZZ whom it may concern.

Be it known that 1, JOHN TALCOTT Wants, of Scottsville, in the county of Monroe and State of New York, have invented a new and Improved Truss for Buildings or Bridges, of which the following is a full, clear, and err.- act description.

The object of the invention is to provide a new and improved truss for buildings COllb bining simplicity with great strength, and at the same time dispensing with metallic braces, thus making it a Very cheap structure.

The invention consists of two parallel arches formed of bent boards or any material used in building and connected with each other by posts and braces.

.The invention also consists of certain parts I and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement with parts broken out. Fig. l is an enlarged side elevation, partly in section, of the.

trusssupports, and Fig. 3 is an end elevation of the same. i

The piers A and A support the posts l3 and B'", and are provided on their inn er sideswith steps 13*, into which fit the lower ends of the inner arch,'C, made of any desired number of boards fastened together with spikes, nails, or other means, The ends of the last boards forin steps, as shown in Fi 2,iltting into the steps 13 of the posts B and n respectively. The ends of the arch G are secured in place on the posts B and B by bolts D, passing through the said posts and the arch C. Parallel with the arch G is placed a second arch, E, made likewise of bent boards or any other material, and connected with the inner arch, C, by posts l placed radially in the arches C and E, and fastenedin the same by spilres or other means. The lower ends, it, of the outer arch, E, are slightly curved outward, as is plainly shown in Fig. 1. I

suitable braces, G, are placed between the posts F and the arches C and E. The last posts, F, do not extend to the inner arch, 0,

but rest on top of the horizontal beams it, supported on top of the respective post B or B. of the arches C and E also rest with their lower ends on the horizontal beams H. Each of the latter is supported near its outer end by abrace, l, resting at its lower end on the outside of the respective post]; or B, and 011 its inner end by the plank X, fitted into the posts B or 3, and filling the space between the foot of the arches G C, The top of the outer arch, ll, is covered with a roofing, .l', of any suitable construction.

ln erecting a building I prefer to build a truss with two inner and two outer arches, C C and ll E, placed alongside of each other, as shown in Fig; 3, so-tliat theqaosts l and the braces G, as well as the beams ll, project between the two arches, and are secured to the same by spikes before mentioned. A truss thus constructed forms one section of the building" and as man T sections ina be eniployed desired, being placed suitable distances apart, and the roofing J stretching from one section to the other. Ornamental side pieces, it, may be secured. under the ends of the roof J, as shown in Fig. 1. Thus it will be seen that a building may be formed by a number of trusses constructed as above de-' scribed, said building being very strong, sin1- ple in construction, and not requiring any metallic braces or rods in order to strengthen it. The truss A is balanced in such a main ner that all side push on the foot of the posts 18 and B is reduced to a minimum. The beams ll act as levers, being held down by the outer arch, l lfwhile the'boards I will hold the foot-of the posts l3 B against the foot of the arches U, thereby taking any outward push oft from the said posts.

Having thus fully described my invention, 1 claim as new and desire to secure by Letters Patent? 1. The combination, with an inner arch and main posts supporting the same, of an outer arch held concentric to the inner arch and curved outwardly at its lower ends, radial posts secured to the said two arches, and

braces held between the said radial posts and arches, substantially as shown and described. The combination, with main posts and The last braces, G and G on each end horizontal beams supported on the said posts, zontal beams and fastened to the lower faces I of an inner arch secured with its ends on the of the radial posts at their upper ends, sub- 10 said posts, and an outer arch held concentric stantially as shown and described.

to the inner arch and fastened to the same by w v 1 radial posts, the ends of the said outer arch JOHN rlALbo-T W ELLb' being supported on the said horizontal beams, Witnesses:

and the Vertical bars G G2 extending from JAMES L. COX,
